I wrote a plugin-based reporting program under Delphi 6. The reports are
contained in DLLs which the main EXE loads. The user can pick a report,
configure, and print, etc.

I recently had to make a bug fix to this program and some DLLs so i loaded
it into D7 and did the changes, compiled, and re-deployed. A user reported
back that everything works until he goes to print the report and then he
sees an access violation and no printed output.

after debugging last night on his machine, which is running Windws 98 SE, i
narrowed the crash down to a call to EndDoc in my modified TPrinter
component.

it prints fine under Win2000 and WinXP.

As i said, this always worked out of D6, but now there seems to be some sort
of incompatibility with D7/TPrinter and Win98.

Has anyone encountered this? I wrote a new component that descends from
TPrinter, but the problem area is calling EndDoc which of course i didn't
modify at all.
