Same problem here. Crashes only in WinNT4 sp6, when it tries
to display the classbrowser tooltip.

I have the same problem on an NT4.0 platform. This did not
occur on $.9.8.x
Logged In: NO
had the same problem with the code completion.
Switched off the code completion cache, problem is gone.
Hope this helps somehow.

what would help is why this error occurs?
on w2k I don't have that problem
Logged In: NO
Seems like the tooltip CreateWindowExA fails because of
extended style attribute WS_EX_LAYERED. Maybe this attribute
is not supported on NT4

good catch.
can you reproduce it?
can you test a test build when I correct it?
I don't have nt machines anymore
Logged In: NO
It's 100% reproducible. I can do the test run tomorrow or
next week. (nt only at work)

please try this version:
http://www.castlesofpoland.com/dev-cpp/devcpp.exe
http://www.castlesofpoland.com/dev-cpp/devcpp.map
and let me know?

It doesn't generate the exception anymore, but the tooltip
is not shown either.
No call to CreateWindowEx is made. (breakpointed it in OllyDbg)
Class browsing and code completion is enabled in the editor
options.

that's not good. It should still call createwindow. With
previous version your debugger showed you that createwindow
was called and now it's not? I've just added one line and
didn't remove anything
Logged In: YES

Yes, with previous version, createwindow was called, with
this new version no call is made.
The machine I tried it on, had an older version of dev-cpp
installed. Maybe it interfered somehow. On monday I will
install a clean 4.9.9.2 and try again the debug exe in that
environment.

Sorry, the debug exe is indeed working and the tooltip is
shown correctly now.
The problem was that 4.9.9.2 does not display the tooltip
after you type "function(", but only after the next keypress
after that...

is it ok to close this bug report or are there any remaining
issues?
