Please describe the problem:
When I open up any account, instead of a single pixel black line between each transaction, there is a single pixel black line above and below each transaction with a thick (2 pixel) gray bar between each transaction. Clicking on any transaction causes the entire window to repaint and display the list correctly with the transactions abutting (separated by only a single 1 pixel black line). However, since it is only extra space being removed, the list becomes shorter and it does not repaint the area now below the bottom of the list to gray as it should. Resizing the window slightly causes this part to repaint as well.

Steps to reproduce:
1. Open GnuCash
2. Double click on any account from the accounts tree
3. Notice thick gray bars between every transaction
4. Click on one and watch the whole window change


Actual results:
See the problem description

Expected results:
I would expect the account tab to display correctly without the gray bars from the start.

Does this happen every time?
Yes. It happens for each tab I open. Tabs stay correctly displayed as long as they are open (even if I switch to other tabs and back), but if I close them and reopen them it happens again. It also happens again if I close and reopen the program even to tabs that start open because I left them open when I closed the program.

Other information:
I'm not sure if this is a general probably or specific to the Windows port I'm used (which I installed from the binary installer). This is on XP SP3.
