I suspect this is something that my VBA code is doing...
I have a processbook display with some VBA behind it, (talking to AF via a .NET module but I don't think that is relevant). After a period of use, the display stops working. mouse clicks anywhere in Processbook just result in the title bar flashing. I can hover over items in the toolbars and menu bar but clicking them just flashes the title bar. The VBA environment title bar also flashes but the VBA environment responds. I am not paused within any VBA (hitting the play button/F5 gives the Macro dialog for me to choose which macro to run). To get it all back, I have to kill PB from the Task Manager and restart it. This is a real pain for me and will be more so for the customer!
Any ideas what may be causing this?
