Well... I made a video to show what happens. I trying to pan horizontally. Once I stop moving in one direction, it starts moving in another direction.

Well, without having SBPE I think I've hit my limit with that one. It took me a while to find a title (rFactor) I own that behaved like you were experiencing...and that last code works great in rF except for a small detail - the rate of panning increases the longer you hold the button - it doesn't move at a constant rate. If I wanted to I could fix that, but that's not what you're experiencing.

Not sure what else to try at this point. Good luck. :\

Just to follow up in case someone with the same issue finds this. The cause is most likely the lack of absolute mouse coordinate support in the SBPE 3D views. There's a known issue with them in a virtualized environment, but I did think that T.A.R.G.E.T. would use them for keyboard/mouse input. (Seems like double the work?)

My solution, (thanks to Superbus), over at the eSim forum is to use "Xpadder", $9USD, instead of T.A.R.G.E.T. It allows me to map the mouse to HAT1 and toggle the "mode" with multiple buttons.

Hello. It seems we got a common enemy

found a way to make the 2 mouse cursors one.
(you need to alter target.tmh file at line 193 (or 192). Set PlugMouse(0)

I found some code that resets the adding up of coordinates to zero (so it starts again without the big hops)

We are currently handling it here:

I know the code for stopping the adding. But I lack the skills to CHAIN DELAY both the code that stops calculating and the continuing of the mouse cursor in the same action. (as you can see if you follow the link)
My idea is to cycle both stop adding/subtracting code, with the continuing of the mouse cursor.
I will take bets it can be done.
But for now my code stops movement period.
Maybe we all hold pieces of the same puzzle, but we don't know it

Update: Synkc gave me great code that works.
