Description of problem:Kmail window has 3 panes whose sizes can be changed by 
dragging the pane splitter. If a pane is completely minimized by dragging this 
splitter, it is very difficult to undo the operation by dragging the splitter 
in the opposite direction. In fact initially I thought it was impossible - it 
took a lot of trying to get the mouse pointer to grab hold of the splitter 
once one of the panes was minimized. 
 
 
Version-Release number of selected component (if applicable):Kmail 1.8 using 
KDE 3.4.0-6 (Red Hat) 
 
 
How reproducible: Always, especially between the message-list and 
message-preview panes (i.e., using the horizontal pane splitter.) 
 
 
Steps to Reproduce: 
1.grab the horizontal splitter with mouse and push all the way up so 
message-list pane disappears altogether. 
2.let splitter go (now we have 2 panes) 
3.try to grab the splitter again to pull it down from above the 
message-preview pane (so as to expose the message-list pane again) 
 
Actual results:The splitter is difficult (if not impossible) to pull down 
 
 
Expected results:Pulling down the splitter to expose the message-list pane 
again should be as easy as pushing it up (the reverse) 
 
 
Additional info: The average user will give up in frustration. I ended up 
deleting the appropriate portion of kmailrc to revert to the default pane 
setup. When retesting I found that it was possible to reverse but difficult.
