I'm having similar problems with a usb mouse. When I click (even with the mouse removed from any surface), the pointer jumps (sometimes a little, somtimes halfway across the screen). Using the shoulder button for mouse clicks works well though. The shoulder button worked the first time I set it up, next time I ran dosbox it had the same problem as the mouse.

Probably related to the feature/bug of how SDL handles custom pointers. When using a custom pointer, it doesn't sync the touchscreen and mouse the way it does when using a regular pointer. There's a workaround, but it needs to be implemented in every piece of software that uses SDL.
(It's a feature because it was actually designed like that on purpose. It's a bug because I disagree with the design )

It seems to work fine... in Ubuntu (on the Pandora). Is it a difference with SDL versions then?

I found out was causes the annoying behaviour of the mouse coursor in dosBox:

It's the ticked setting "retain aspect ratio" found in dboxFE -> System -> Render. Putting a checkmark here will display the dos game without any black borders at the top or bottom and makes it use all 480 pixel vertically. That's reallyreallyreally great looking but on the downside the nub-input is beeing f**ed up.

Is ther any way you could please fix that, Pickle? The scaling looks so much better than the smaller screen surrounded by big black borders..


EDIT: Actually, it seems that the 'retain aspect ratio' setting makes totally sense. Without it, the video output is distorted (at least with all games I tried: Colonization, alone in the dark 1 and 2, Quarantine, magic carpet, Master of orion, master of magic). The ratio should be 4:3 which it isn't if the 'retain aspect ratio' isn't checked.

From http://www.dosbox.com/wiki/Dosbox.conf :

aspect = true | false
Do aspect correction. It only affects non-square pixel modes like VGA Mode 13h, which has a resolution of 320x200 pixels and is used by many DOS games (DOOM, etc). Recommended as such games were designed for 4:3 displays, and without aspect correction will look distorted and not as the developer intended.

Default is false.

Bump bump! Pickle, could you please have a look and fix the issue with the wrong aspect ratio/ incorrect nubinput?

Its probably the code used to make the touchscreen usable (absolute) messing up the nub (relative). Dont know when ill have time to debug.

[zapman]

alright. Thanks for acknowleging
