Reported by Chau Chee Yang:

I am using Delphi to develop win32 GUI application. My application use GBAK to perform backup and restore operation against Firebird database. As GBAK.EXE is a console program, I try to redirect the GBAK output to my GUI application as instructed in Microsoft KB: http://support.microsoft.com/kb/190351

I have successfully perform the redirection. However, if I backup/restore a BIG database (eg. 100MB in size), my GUI application will show "Not Responding" in windows title during the GBAK operation. As mentioned in the microsoft KB, I suspect GBAK.EXE didn't perform proper flush operation. As thus I report this issue the firebird-devel list.
