Is there a sensible limit to the amount/quantity you can usethe "modeldoc2.ForceRebuild3(true)" trick ?

In my case at a certain moment it crashes my macro. And doing sowithout giving an error message.
When I restart the macro I do get the notification about the macropossibly beeing unstable due to a problem on previous playback ...

This is my situation :

I've got 1 macro that has a playbutton on my menubar.
It functions as a "main menu" for my configurator.
The user has 3 options to pick.

Once the desired product is selected, the main macro unloadsitself, and launches a seperate macro designed to configure/drawthe chosen product.

This macro opens an assy, runs (alters dimensions, features etc)then rebuilds the assy.
After this the macro unloads itself and opens the "mainmenu"-macro.

When i choose to do another config/run, it once again unloadsitself , loads the config macro, runs the config macro and does aforceRebuild. Only this time it crashes the VBA and halts all .

There is quite some time between the 2 rebuilds .. i'm not surewhat goes wrong here ..

Any ideas are allways more then welcome !
