On some of my Macs, dragging a file to SlickEdit window to open seems quite slow (up to 5 seconds) to get the "+" sign, acknowledging that the drag-n-drop operation is recognized). If the "+" does not show, dropping the file fails to open. Quite annoying to wait 5 seconds holding the mouse button to get it to open (albeit faster than using the open dialog).
This is on an ARM Macbook Pro (M1 MAX) with plenty of memory (32GB), running macOS 13 (Ventura), with nothing else running. Same thing happens on a Macbook Air M2.
Any ideas? Thanks in advance!
