Lanschool issues with remote controlling

[MrBrow]

Anyone seeing the following odd behaviour with Lanschool at all? @LanSchoolUK_Adam - have you any thoughts on this at all?

 

 

Running the latest release - 8.0.2.82 - with a LCS and the teacher and pupil on the same subnet.

1. 
   

Lanschool Teacher can see all the pupils in the class and can change view from details view to the thumbnails. Selecting and controlling a pupil machine will work once but if you try to reconnect, Control is greyed out and you cannot connect a second time.

We have also seen that the blue computer icon on the details view then turns grey, assuming this is related the above.

Then, very often, after the teacher disconnects, the pupil machine will become locked, as if the Disable mouse and keyboard is selected but we have released control. The only way to release the pupil machine is to kill the Lanschool process.

Oddly, when you select a pupil in either thumbnail or details view, you cannot deselect a pupil. It's as if the Shift key is being held down - it's not though and you can then multi-select only several pupils. To clear the selection you have to click somewhere else on the pane, not another computer like we have been used to.

 

Update: this appears to be a registry setting called USETOGGLESELECT. Any ideas how this got turned on as its not in the GUI that I can see.

Finally (I think), when controlling a pupil machine, if you minimise the main Lanschool window and have the Remote Control window open, it doesn’t minimise to the taskbar but instead closes and forces you to reopen the main Lanschool window from the task tray. The Remote Control window stays there though.

 

 

Anyone have any ideas at all? This appears to be something that started in version 8.0.2.54 possibly and is still there after the recent upgrade. This doesnt appear to be a global issue - my desktop certainly works as expected but becoming a real problem in 1 particular room, if not more.

Hi @MrBrow - thanks for raising this and sorry to hear about the issues you've been having since updating to v8.0.2.54.

 

This isn't one I've come across (we've just updated all our laptops, VM's, servers and other devices to v8.0.2.82 in preparation for BETT) but if you give me 24 hours I'll try and replicate it per your detailed instructions and see what results we get.

 

Since you mentioned it is only impacting one room and not another, can you let me know the hardware spec, OS version etc. of the affected machines?

 

Could I ask you to PM me your school/college details so we can set up a bug report ticket anyway, in case it needs to go to dev? Cheers.

Thanks @LanSchoolUK_Adam I'll send a PM.

 

I am yet to reinstall the teacher computer but have tried a couple of older versions of the Teacher client. Nothing changes. Annoyingly I cannot replicate the 'connect once only and not again' issue on my technician machine so it really could just be that one room. I wouldnt be surprised that a reinstall clears the problem but then there would be no explaination as to why it happened.

 

Spec of problem room: Dell Optiplex 3040 (so really not that old. i3, 8GB Ram, latest drivers, reliable network, same VLAN (same switch), same room.
