Can't open dialogs in GUI

[ts1]

Hello,

with the new IA X6, I can't open any dialogs. No message, no action.
Wether old dialog created with X2, new dialogs created by the X6 wizard, dialogs from expamle project: no action, no message.
It's quite error prone to manually edit the *.dfm file.
Is there a more convenient way?

Thanks,
Thomas
