Amount and type of RAM: 512MB
Video board w/ RAM amount and type: Radeon 8500 64MB

Operating system: WinXP Pro SP 1 EN
Game name (and version, if applicable): Impulse Tracker 2.14 p3
Description of problem:
IT works in text mode in dos of course. On default conf of VSDMSOUND it works fine, except little window with graphic visualization of sample - its blank. When I turn on "VESA Basic Mode" the visualization of sample is finally visable, but IT began to hiccup. After turning off VESA mode, sound back to normal.

Sound mode used: Standard Configuration (IT uses SB16 emulation).
Video mode: DOS/Text mode
Version of emulator: 2.10

There is a bug with WinXP Pro SP1 and VDMSound that causes this. You should turn off "Enable basic VESA emulation" and instead quickly hit Alt+Enter when the VDMSound initialization screen comes up.
