Record a .gif animation to show (visually) what's wrong...

My thumbnail sizes are 237x237,See in the third row the last thumbnail being not selected properly.

It's not about a specific row number, it's about the ones that are not fully visible. They don't activate the same way when just hovering over them.
Can confirm this behavior...

Yep, fix comes.

Seems to be fixed with 0102

Multi selecting thumbnails has been fixed, but individual thumbnail hovering is not fixed -- hover on each thumbnail with mouse without pressing any key like Ctrl or Shift they are not selected.

Works fine here?

I can reproduce a problem when I turn off the file info tips (Configuration | Information | File Info Tips & Hover Box | Show file info tips). Have you done this as well?

Yes

It should be fixed in the next beta.
