I found a thread that addresses my problem, but with an unworkable solution. https://forums.pokerstrategy.com/forum/thread.php?threadid=316901. (Maybe I inserted that incorrectly.) When I open equilab and then open the hand chart, the chart only fills about 20% box. This problem seems to arise because I'm using a laptop with a higher resolution. The solution offered is change the scale from 250% to 100%. This works for equilab, but it screws the hell out of everything else.
This fix was found during Windows 8. Has anybody found a fix that works for laptops?
