Kevin,

I've found this is a problem with gambas/qt, I've many many many dozens of 
forms in my project (lost count), some of which pull quite a bit of data from 
a postgresql backend.

As a work-a-round suggested by someone else on the list - on forms which are 
'doing alot' at startup - I put a timer on the form and in timer1_timer, put 
all the code you want to execute once the gui is visible, and set its interval 
to an appropriate amount to let the gui finish first.

Works a treat - just experiment with the time required.

Regards

Richard
