EDIT:
There was an issue with my hosting and migrating my site to a new server. It's back up now.
Will see it later, thanks.
I've read that it's possible to have multiple Java version installed on an OS, but for the life of me I can't figure out how to switch between versions. The env vars/path/registry hack solution I found on the net are not working for me and it'll always default to the latest (Java 7), so my Java 6 tools suffered.
A temporary solution to my dilemma is installing Linux Mint LXDE on VirtualBox, then install OpenJDK/JRE 7 on top of it (wow, a 4gb install just to use a 58kb tool...). It works, though the tool is screaming about win registry API missing and I have to transfer the save files manually between the 2 OS
Unfortunately, there's one kink of the solution. Because of X window's font handling differs to that of Windows, over half of the GUI is out of view. While other tabs have scroll bars to compensate, the Player tab doesn't, and I can't access 3/4 of the settings there.
So here I am pleading to Corrodias to add a scroll bar to the Player tab, and, if possible, making the main window vertical resolution defaults to the current screen vertical resolution minus 32 pixels (to compensate for the taskbar).
