Status: Verified
SYMPTOM(s):
Running multiple parent-child windows causes problems upon closing.
Multiple windows running non-persistent
CAUSE:
When using WAIT-FOR statements in an application, programmers should take precautions to make sure that only one WAIT-FOR is "active" at any one time. The PROGRESS 4GL does not do this kind of housekeeping automatically.
FIX:
If it is imperative that more than one window be active in your application at one time, then use persistent procedures rather than windows created with WAIT-FORs.
