Auto-completion issue Servoy 5.0.1

Auto-complete doesn’t work when typing -for example- ‘a’ CNTRL-SPACEBAR.
It strangly doesn’t occur in every Servoy 5.0.1 instance (on same machine).
I’dd say there should be a prefs setting for this, but I can’t find it… :?
Does someone have any idea how to fix this?

Servoy 5.0.1 - build 861
Windows Server 2003 R2

what exactly are you trying to complete?

does d[CTRL-SPACE] work for getting the databaseManager?
