There is little hope for issue #1 since it is indeed a Vista bug, not mIRC. However *I* no longer have the issue, so it might have been resolved in a windows update but I cannot confirm that. As I mentioned above, it might also be related to specific UI settings.. I forget what changed between now and the last time I reproduced it, but I haven't seen it since my reformat.
For issue #2 you'll have to show steps on reproducing it I think. If you can provide a consistent way to show the issue, it will help Khaled fix the bug.
