Not too sure how to word this but when I click on my guy in the bottom left and go to the next page and click "spellbook" it clicks it like, 8 times even if I just click once. If I hold the mouse button down on it, it just flashes between the 2 really fast as if I were spamming left click. I did raise the cycle speed to make the game run smoother but lowering it didnt seem help. Thanks in advance.

Interesting. The "Spellbook" box is supposed to be a toggle between spells and equipment - but it doesn't seem to quite work as it should. This is what I observe: If you click "Spellbook", one of three things may happen (depending on the duration of your mouse click?):
- nothing, or
- it switches rapidly between spells and equipment (as long as you keep the mouse button pressed), and when you release the button, the switching stops at either spells or equipment. I suppose you have a 50% probability that it stops where you want it to stop. Or
- it works as intended.
For getting the third possibility, you may have to find the "sweet spot" between clicking too short (possibility 1) and too long (possibility 2). At least you can get to your spells or your equipment with a little patience :-).

I've tested it for the GOG version, and for Arena Setup, no obvious difference. DOSBox configuration? Would Arena 1.06 work better? I don't know. Does anyone remember, if this problem existed in the past, when Arena was running on a native DOS PC? My guess would be no, because I think I would remember it, as I played Arena extensively for a period of time on such a PC then, and would probably have noticed it (or not, who knows).

Be this as it may, the problem is manageable (at least for me :-)).
