No, I use USB mouse
Looks like problem is not in JPen.
I've loaded JPen free version of alchemy (for 006 env), as you suggested, from post632.html#p632 thread
and run this jar in 006 environment - Alchemy loads, mentioned errors disapears, BUT still there is no content in Alchemy window neither any controls/hotkeys available.
It seems I have some lack of mouse support dependent on Linux configuration.
But there is no other soft with such a problem on my box.
Thanks for investigation. I'll post the solution here if I'll find
