To further clarify, it’s behaving as if the EmEditor window size isn’t being recognized correctly. The cursor changes to the pointer that should work in the line number section too soon, and when I click at that point, it highlights a line below the pointer, instead of the one the pointer arrow points to.

e.g. If I try to move the cursor to the line number for line 20, it changes to a pointer while it is still over the text pane of the emeditor window, and if I click the mouse, it highlights line 21 or 22, not line 20.

Any help would be appreciated, as this is one of my most-used features of the product.
