CAUSE:
Bug# 20031119-043
CAUSE:
This is a bug which is known to occur if a dynamic widget is deleted from within a persistent trigger for that widget (For example, a trigger on a menu-item widget destroying that menu-item).
In such cases the memory area where procedure parameters are stored can get corrupted, resulting in a hanging or crashing client.
FIX:
Upgrade to 9.1E, 10.0B or later release
Workaround:
Modify the code in such a way that widgets are not deleted from within the scope of their own triggers
