PowerPoint files saving as TMP without warning
I'm currently having an issue where PowerPoint files are saving as TMP files rather than PPTX, I'm are not sure what could be causing this to happen.
It doesn't appear to happen at any particular time and we get about 45 per 1 hour period spread across the whole hour but only during lessons.
It happens from several rooms across the school (all based off the same image however).
It has affected staff and students but much less for the staff.
Our setup is the following;
Windows server 2008 R2 (for student areas)
Windows Server 2003 SP2 (for teaching staff areas)
Sun Microsystems San 7210 (for support staff areas)
Windows 7 X64 SP1
Any thoughts would be appreciated.
Thanks in advance.
