[Wine] broken controls in "Captain Claw" game

[leniviy]

Hi. I want to play the old '97 game "Claw". It installs and runs, but strangly I can't jump in it! No matter what I use, keyboard or gamepad.
Normally, if you tap the spacebar, the character makes a low jump; if you hold the spacebar, he makes a high jump. However, under wine all jumps are low. Other movements work fine though.
I even tried to run the game under winxp guest in VirtualBox, but had the same problem. reassigning keys doesn't help.
I just don't get it: when holding the movement keys, the char moves steadily. That means, the game knows, that I hold the key. Why it doesn't see that when I hold the "jump" key?
Multimedia timers maybe?
