I seems to be having trouble getting Qt Designer to work on Windows 7. It seems like it works the first time I run Designer, but after that it appears in the Task Manager with no window every appearing. I have tried different compatibility modes, searched the web, etc. and found no resolution. I could be wrong about it working the first time. I thought I had tried it when I recently installed 4.8.0 on this new computer. When it did not work yesterday, I ended up trying 4.7.1 that I copied from another computer. It worked, so I installed 4.7.1 and it did not work. I tried the one from the other computer and it did not work. I wonder what it could be! Any help is greatly appreciated! Thank you in advance!
