Mouse mapping bug

[fpalazzolo]

I have found one app where some of the mouse mapping is incorrect under js-dos, but it works fine in DOSBox-0.74 and DOSBox-r4006. It's probably a bug in em-dosbox. It appears to be related to the DOS interrupt 0x33 that sets the mouse extents AX=7 and AX=8. There is an example app at http://cups.avoidspikes.com/ ... if you dismiss the opening dialog and then select Graphs->Path Integral. Then left-click in the upper left plot area to create a polyline. You can see the mousedown and the mousedrag coordinates don't match. I should probably create an issue with the em-dosbox github, but I haven't built em-dosbox yet. Does your build of em-dosbox uses SDL or SDL2 support? It might be related to that. Thanks!

The behavior is slightly different between Chrome and Firefox here as well. I have recently built em-DOSbox so I will look into it myself.

Please reopen if still exists

This is because program set region where mouse should operate, and it's not supported by js-dos. However you can use autolock: true feature of js-dos v7.
