|A few things you can try:|
- Since HTA's are rendered by IE, make sure all instances of iexplore.exe and mshta.exe are terminated. This is especially important if you have some popup blocker installed.
- Use JScript/VBScript to resize and reposition the window
- Make sure the WINDOWSTATE property isn't MINIMIZE
If those don't do it, I'd need to see what your script was doing.
