weird error using RB with Term Services

rbuser

I have a Delphi app using RB. Everything works fine when the Report Explorer
is opened and a report is Previewed when the app is running from the server
machine's desktop. However, some users access the same app on the same
server over the Internet using Microsoft Terminal Services (TS) ActiveX
control in a web browser. The Report Explorer opens, but when they try to
Preview (or Print) a report, an error message dialog pops up with "Canvas
does not allow drawing". Usually followed by a few AV's and a "Privledged
instruction".

DOes anyone have any clue as to why the Report previews correctly on the
desktop but not over TS?

What version of RB? Check to make sure that a default printer is installed.
In RB 6, we added a 'Screen' printer option in the PrinterSetup object of
the report, so you can preview without needing a printer to be installed.

By using 'Screen' as the printer, then the screen canvas is used to generate
a report, ie. calculating text widths, text heights and such.
