TestComplete freezing while using it (building a scenario...)

Hi,

I just upgraded to 11.20 version of TC and TE.

Since de 11.10 version I have very long stops while TC is not responding to windows anymore.

Especially in TestedApps, or going into Scripts, Events or utsing autocompletion.

I have enough RAM I think and the local network, on with there is the project suite, is ok.

Any help would be much appreciated
