Debugger problem

[Piko]

After starting new project with one empty form everything works fine
on first run. But after second run form disappear. After debugger reset
running application (form) is visible again.

If I manually Reset debugger (Run/Reset debugger) after each run everything
works fine. I was played with debugger options but nothing helps.

After turning "Show message on stop" in debugger options message appear after
program stop, but problem still exist on next run.

I get this message in addition to this error randomly every time I hit RUN in Lazarus (fresh install, Vista 32-bit, no spaces in path).

The appearance is random - it can be either one of the above, or just nothing happens (you need to reset the debugger to continue), but only one in each five attempts the debugger runs. When the debugger does run properly (about 20% probability every time you hit RUN), putting mouse cursor on a variable says that "this" is not aggregate.

Haven't managed to debug anything in Lazarus yet.
