          Platform: PC
        OS/Version: Linux

Bug summary isn't quite clear but I don't know how to say it in other words.
Screenshots may help to imagine it better.
Bug is reproducible with Micro-Cap 7.1.0.0. Unfortunately there are no more
legal ways to obtain demo version of 7th release so I've tested it a bit in my
university. Demo of the latest version is only available but I can't reproduce
the bug with MC9.

Screenshots description:

2. Micro-Cap is running on wine. There's override of comctl32.dll.
3. Micro-Cap is running on Windows XP.
