Hi,
I recently updated from 3.X.XX to 4.2.6.
Previously I could drag the bottom of the Search results window upwards so that it shared the available space with the Downloads window. With the windows divided like this, each list had its own scroll bar which I could use to scroll from the first to the last line without re-sizing either of the windows.
Now on 4.2.6 I am unable to drag the bottom of the SEARCH RESULTS window, the part with the Downloads, Browse Host and Stop icons, upwards. When I drag it, it starts to move then stops.

Is this a bug, design intent ?
Can I change this behaviour back to the old way ?

You should still be able to resize it. What skin are you using? You can see which by going to View -> Apply Skins. The one you're using is selected. You can also try changing skins to see if this fixes it.

I'm using the skin Limewire Theme, I changed to the Classic Theme but it makes no difference, still can't drag the Search Results window upwards.

When I started up today, initially with the Search Tabs area empty, I found I can drag the bottom of the Search Results window upwards much further than after I have entered 25 different Filename searches, which results in 5 layers of Search Tabs.

It looks like the minimum size of the Search Results window includes the Search Tabs area, and the minimum size allowed is 19 llines of text visible in the window, then it stops.

As test, I deleted 4 of the Search Tabs, so that the number of lines of Tabs reduces from 5 to 4, now I can drag the bottom of the Search Results window upto 18 lines of visible text.
