What I've found to work was to click "Hide window" While running other programs. To avoid that happening. To bring back the window hit the same button "Hide window".
OK I figured out what your doing wrong. See where it asks for the keyboard keys? Click "Set Key" and do what it asks. It will prevent that from happening and you can use the hide window mode, or just have other windows overlaying on top of the game. I just tested it.
It takes a lot of testing! So play around with it. If I get any good working options I'll share.
OK for some of you, I read on MixLife's forums from a user "Neko" that the best way to do your health regeneration would be like so. Just so everyone knows that user gets all the credit.
Auto-regen, for example: You regen key is on '6', and you want to regen when your hp is lower than 40%
You must add these,
1. Choose 'Relax'
2. Choose number '6'
3. HP >= 0, HP <= 40
4. MP >= 0, MP <= 100
5. Put the name of this setting (EX: Regen-HP) and click OK
OR if you want to regen when your character MP is lower than 10% You must swith from HP to MP, Like
HP >= 0, HP <=100
MP >= 0, MP <= 30
Remember, Regen-HP is apart from Regen-MP. If you want to regen both, You must add the setting 2 times.
