Written text disappears.
I have a Promethean board in a mobile classroom with laptops running Active Primary 2 and 3. It’s an outside wall and no power cables run behind it.
Writing on the board and the text will suddenly disappear. Going to the next page and back to the first will sometimes bring it back but not always. Saving a flipchart usually omits the last page.
I’ve tried so far from working classrooms.
4 laptops and lots of pens.
Various drivers including the latest and several versions of Active Primary.
Swapped out the power supply.
Swapped out both power cables.
Connected a USB cable direct from laptop to the board to rule out the av/usb wall socket and wiring in the trunking.
Updated firmware on the first board.
Swapped the two Active boards over.
Everything has been changed and it still does the same thing.
Any thoughts or suggestions would be welcome.
Where is the flip chart file being read from? any usb memory sticks plugged into machine if so remove them and try again.
If the text is getting to the software then the board is working as it should, I'd ditch active primary 2/3 entirely and switch to Inspire(free upgrade via the promethean website) anyway with or without this issue, I find it to be pretty stable and has far fewer quirks.
Not quite sure what could be causing this in a specific room, I'd say look at the network connection in addition to plexer's suggestion although it should have no bearing what so ever
It happens on a new clean page. Just write random text and at some point on the page the text will disappear.
Any additional usb devices or specifically memory sticks inserted?
Not at any stage of diagnostics. Nice thought but I,ve taken this down to the very basics.

At this time of the year I doubt it is any sort of heating starting/stopping causing this.
Since the text appears on the screen it has clearly been detected by the laptop(s) so for it to disappear something must be overriding the laptop software...that is why I wonder if there is an external device also linked to the board (the ActivTablet or ActivSlate will sync to the board without any addition hardware) that is cancelling the text...
we had similar and other wierd issues with a board, turned out to be faulty usb stick.
Does it do the same on another board?
If the text is sometimes returning when changing page and back then I'd say its a software glitch.
Try using MS Paint instead of activ primary to test it or give inspire a go
You say that you have tried 4 different laptops (known to work on other boards I assume) and even swapped the ActivBoard out with another and replaced cables, pens etc, which only leaves one thing - the projector?? Just wondering if it is something to do with the refresh of the projector - would be interesting to know if you mirror the displays, does the copy of ActivPrimary displayed on the laptop screen display the annotations but the projector doesn't?
First thing I would try first though because it is easier, go into ActivPrimary's settings, select "Flipchart objects" and remove the tick from "Lines and Shapes" in the High Quality section - some Graphics cards can't cope with this setting and display similar issues to what you are seeing.
I went to the school today and tested.
The text disappears from the laptop screen at the same time as the board. I removed the tick from "Lines and Shapes" and the result is still the same.
I've even disconnected the power lead to the laptop and run on battery to eliminate power problems.
I'm at a complete loss as to what to try next.
Theres something strange happening here, please can you check what versions of the software you are running and which OS?
Also, did you confirm that the laptops work on other ActivBoards without issue?
First laptop was the classroom laptop which has always worked with the board until the problems started. I tested with two other laptops taken from working classroom whiteboards which show the same symptoms in this class. Took back to the original classrooms and work fine. The fourth laptop was a clean install with the latest drivers downloaded the day I tested and latest Active Primary 3 as supplied by the Promethean helpline via email. They are XP SP3 with all updates. I can’t get version numbers until I am next in on Wednesday but given all the versions I have tried it’s not drivers or software I think.

The ultimate test is to exchange the board with a working one from another room to see if the issue follows the board - we need to isolate the issue if we can as at present there are too many variables.
