maybe the released versions of my scripts dont work with this beta, but i made some small changes and all of them still work for me right now.
The changes arent major and only in 2 scripts files did i need to change anything.
So i dont think 3rd party apps will have any serious issues, if my scripts can still be made to work, im sure anyone elses code can be modified or updated to work.
If you want to make zoom buttons in autoit its pretty easy. Take a look at the igcontrol.au3 script, the zoom buttons on there still work.
If you want 2 seperate buttons, also take a look at the exitfs.au3 script for reference on creating buttons and substute the code for zooming in and out instead of what it presently does.
I can also just send you updated versions of the scripts too, PM me if you want them.
