App hangs after 2nd call of a hydra plugin (delphi)

Hello,

I have written several (visual) delphi hydra plugins (XE6) that all have the same problem. They work great when I call them the first time. When I then close the plugin and restart it, the complete application hangs.

First I thought, that a special component set (Raize components) have problems with the hydra model, but I removed all Rz components from the plugin and in some plugins this helped, in others it did not.

So, any idea where to start my investigation on this problem ?

By the way. these components worked for months perfectly under Delphi 2010. Then I recompiled them with XE6 and my problems began.

Thanks for your help !

Best Regards

Thomas

Ok, please forget it !

The problems were caused by Raize components. They forgot a destructor.
Thanks
