@hying

I can confirm this bug (dissassemble command seems to be not send to debug).

It only happens, if I reach the breakpoint the first time and then step over it with "continue" ("STRG+F7" or "F8"), that means if the actual and the former breakpoint are at the same line in source-code. If I step over the breakpoint ("F7") and leave the source-code line, the next hit sends the dissassemble command.

Can you please file a bug-report at berlios, so it can't be lost ?

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

I also filed a bug reporting the incorrect change of "symbols" panel we discussed before in this post
