Delphi 2007 -- Access Violation at address 00000000. Read of address 00000000.

[Richard Morey]

Hi --

I have just installed D2007 on a Windows 2003 Server machine and I often get
an "Access Violation at address 00000000. Read of address 00000000." error
message randomly when I am working in the IDE. I have to shit down Delphi
and restart it to get rid of the error. When I click on DETAILS I get the
info below:

If anyone could suggest a solution to this problem that would be great.

Those details seem to indicate you're closing down the IDE:

If you're not, something else is. Do you have any third party
tools/components installed into the IDE?

Hi --

I don't have any other third party components installed other than what was
installed with D2007.

Interesting that you said it looks like I'm trying to close down the IDE --
When I click FILE --> CLOSE ALL the IDE hangs. When that happens I have to
force close the IDE using the END TASK button in the task manager (it opens
back up ok). The IDE does, however, exit ok!

Thanks

Rich
