[texworks] mouse-wheel / slider cause TeXworks inmediate crash, issue broadens

[Paul A Norman]

Cool great you found it, will try and check it out later.

This project is using an interesting editor component under Qt which gives

or have major existing  Tw code compatibility issues.

Any way for your viewing pleasure :) here it is
