I've never been able to resize the Search window either -- it probably can't be. However, if you hover your mouse c ursor over the comment, a pop-up version will show that you can read in entirety.
You can't resize the window, but you can resize the columns within the window, and make the comment box large enough to read.
Newb question here. Basically I'm confused that I can't expand the width of the LFG window. The comments are always cutoff and unreadable. Is it not possible or am I missing something?
