When I try to open Qt Creator, it loads fine but after a couple of seconds, the application window becomes unresponsive and turns gray. I can move the window around, but cannot interact with it. It remains like this indefinitely.
The same thing happens if I try to open a Qt project file with Qt Creator.
And if I try to close the window, I get a dialog box that reads:
This Window is not responding Do you want to force the application to exit, or wait for it to respond?
This happened all of a sudden, while I was working on a Qt Creator project. I don't remember making any change to the Qt Creator installation either.
Among a few things that I have already tried are:
- Restart my machine
- Uninstall and reinstall Qt Creator (using Ubuntu Software Centre)
What else should I try to solve this problem?
