I found another issue in Microsoft Edge. I don't know where to report or comment it to Microsoft.
I didn't want to make a C2 bug because I know it isn't C2 because it works properly in Chrome.
I did test it in Firefox, but Firefox just increases browser scale, and not the game scale.
I was having trouble in Edge with key press before, not sure if it has been fixed.
This is touch press. I am also had the same issue with mouse that I did with Touch.
Microsoft Edge 40.15063.0.0
Microsoft EdgeHTML 15.15063
C2 247 (64-bit)
When using "Example:Touch - zooming"
that C2 comes with.
Edge sometimes has trouble detecting when an onscreen touch/Mouse ends.
If you touch/click the screen and slide down to the Debugger and remove the touch, it will keep the touch/mouse active.
I had 3+ different touch IDs in my debugger at once and wasn't touching my screen.
