Weird error, Will it have side-effects?

[AntonJ3000]

I just got this error:

Warning: a CMapClass is being deleted but is still referenced by a CMapDoc.
Please tell a programmer.
Click Yes to write a minidump and continue.
Click No to ignore.

So I clicked No, then I got this.

ProcessNotifyList: encountered a deleted object. Tell a programmer.

And after I clicked OK I could map as normal again... Just wondering, If I save this, Will I have some weird side-effects in my map?

And nej is swedish because I have a swedish Windows XP
