Delphi Class Completion (Ctl-Shft-C) Stops Working

Suddenly, pressing Ctl-Shft-C in the Delphi XE2 IDE stopped working.  You could press that magic key combination all day and nothing would happen.  It took hours to figure out what the problem was.

I had installed update 4 for Delphi XE2, which contained, among other things, something called AQTime.  This appears to be some kind of application profiler.  Anyway, it was AQTime that was interfering with class completion.  A quick trip to Control Panel to uninstall the offending bit of software and everything went back to normal.

    I don’t believe this is the full answer. I suddenly started having this problem in Xe2. So in order to get around it, I collected my units into a vcl app and loaded with XE. I did my edits in XE and compile in XE2 (FMX). Suddently XE2 started working again. A few hours later it broke again. Loading back up in XE found - IT WAS BROKEN THERE TOO. Not to be outdone, I said right - load in Delphi 2009 - broken there too!!!! AQTime is certainly not installed in Delphi 2009 and Also other people ahve reported the issue coming back after AQTime has been uninstalled

    I haven’t experience the problem that you are describing. All I know is that when I uninstalled AQtime my problem went away and it hasn’t returned.
