No sound and some visual glitches in Puzzle Pirates (old online multiplayer Java game that otherwise runs well)

Hi! I've found two issues with an old Java based game, Puzzle Pirates. I'm running ReactOS through VirtualBox.

I'm reporting them because otherwise the game works flawlessly, and because it might also affect other Java applications.

1) There is no sound at all, even if the audio drivers are installed and working (the few times they actually work on VirtualBox, that is).

2) Everytime there's a visual update in the game (as in: a character moves, new text appears, etc) and there are multiple windows/programs open in the PC, the game window glitches and draws parts of the game over other windows that are on top.

This happens with all ReactOS builds I've tested: 0.4.11, 0.4.12, 0.4.13 and 0.4.14, and with all different video and RAM VM configurations.

Steps to download and open the game:

1) Download from http://download.greyhavens.co/yoclient/puzzlepirates-fullinstall.exe

2) Install the game. Once it's installed, you have to go to the game's directory (Default: C:\Program Files\Three Rings Design\Puzzle Pirates, then right click the shortcut that says "Play Puzzle Pirates" and click Properties.

3) Go to the Shortcut tab, and edit the Target (1st text box for non-English) from

"C:\Program Files\Three Rings Design\Puzzle Pirates\java\bin\javaw.exe" -jar getdown-dop.jar .

to

"C:\Program Files\Three Rings Design\Puzzle Pirates\java_vm\bin\javaw.exe" -jar getdown-dop.jar .

(You just need to add a "_vm" to java).
