Dynamic creation/free'ing of QuickReports

[StevenK]

I have an application written in Delphi 5 that makes use of standard QuickReports. I am creating them on the fly using something like 'ReportQR := TReportQR.Create(Self)' and then calling 'ReportQR.Free' and setting 'ReportQR := Nil' after use.
This has seemed to work OK up til now but I have just develioped a problem with it - its OK the first five or six times but then creates a problem causing an access violation indicating that the component 'ReportQR' already exists.
Anyone suggest the problem and a solution ?

Are you using try and finally in your code?, because without it, if you have an exeption somewhere in the middle, 'ReportQR.Free' will not be executed.

I failed to mention the use of TRY ... FINALLY but it was indeed in place.
Following the problem I rebuilt the application (not changing code at all) and the problem seemed to resolve itself.
Which begs the question how frequent are troublesome builds like these and how can they be avoided (in case I miss one like this in future) ??
