Hi Andrei, :-/

Have I found a bug?

On the tree side, select ENTIRE COLLECTION. Click on it to show list view of all records on the right-hand side. Then make a multiple selection, using CONTROL+LEFT CLICK, on several records.
When I attempt to scroll down to find further similar records to add to the selection, scrolling merely 'zooms' the font size for Orange DB GUI in and out! Returning to my selection task, if I de-select everything, scrolling return to normal. However, I have to remember to ensure that the fonts are the right size BEFORE doing this, otherwise they are all wrong.

I expect it's been reported already, but if not....
