I haven't played DF for a week, but when now when I start up DF, my laptop screen goes black for 5-10 seconds (with a faint shadow of the screen image pulsing on/off) before returning to "normal".
Except normal means that the process repeats everytime I attempt to make DF the active window or "Start Playing".
Once the screen returns I can use any other program windows, but if I make DF the active window, the screen goes black again for 5-10 seconds. I have to terminate DF from the Task Manager. And of course, I can't think of anything that has changed on my PC since I last successfully ran DF, unless my company has downloaded updates system remotely. Up until now, I've been playing for months without issue.
What I've tried:
1) I have deleted the DF application and folders, downloaded and upzipped the latest version. (I was already running the latest version.)
2) I have tried running in both fullscreen and windowed mode (with default settings and my original init settings of 600x800).
Here's what I think it might be:
My IBM Thinkpad T42 video driver has a setting that allows me to test out new display settings and if the setting it glitchy, the display will automagically revert to the previous configuration. I think it's having problems with some display configuration with DF.
But I don't know why and I certainly don't know how to comfirm my diagnosis nor fix it.
Can anyone help me? Or at least help me help my company's tech support troubleshoot it?
Thanks in advance!
