After running and closing my application, i get the message 'remove classes from memory' when i want to modify a toolbar baseclass (wich i created) in the project manager. This baseclass has a method i added which disables/enables all buttons on it like this:
for y = 1 to this.controlcount
if this.controls[y].class = 'Basespecbutton'
this.controls[y].enabled = .t.
endif
endfor

The message doesn't appear when i want to modify another baseclass from another toolbar wich doesn't have this method

Toolbars are created and added to an array in oapp.init event,
and closed in destroy event from oapp by looping through this array
like this oapp.arBars[x,1].release()

Is this something that shouldn't be happening?
Can anyone give me a hint in what i'm doing wrong here?
