*** This issue has been marked as a duplicate of 25910 ***
Hi Damian, I think that there is a different bugs. Bug 25910 describe that debugger thrown expection when starting. I can't reproduce this bug. But this bug is says that is case when user start debug, then start execution, and again start debug, exception occured. I think that there is 2 ways: reop 25910 or reop this issue. What bug I should reopen?
thanks for fast response generally I prefer to reopen older bugs (25910) in the case, when there is same exception. Very often it is same problem !!! BUT, the 25910 and 2 other important bugs were integrated in 2002/7/29 14:57:18. So for testing of the NB34, you CANNOT use RC1, but some RC2 candidate (at least should be older then 2002/7/29)
OK, I'll get new build and try to test it. But these 3 bugs is integrated on my build too.
it is my fault, I badly updated 25910 bug report but there was other changes in the debugger core offical rc2 will be done tomorrow (8th August 2002) so for testing use please last nb 34 build (it means current day) after rc2 release, use please rc2
