After working out an odd login issue with my Beta 3 installation (thanks for the tips, Fahim!), I decided to give Beta 5 another shot.
My only issue with it so far is an annoying "Range check error" dialog window that pops up if I'm on the "Entry" tab and switch between maximized windows and the Blog window (whether it's maximized or not), or if I go to the "Entry" tab from any of the other tabs. It also happens when I switch between the "Normal" and "HTML" views on the "Entry" tab, and when I restore down/maximize the Blog window or restore it from being minimized (from either the taskbar or to the system tray) if I'm on the "Entry" tab.
Has anyone else run into this issue, and/or do you have any thoughts on how I can solve it? It's pretty annoying.
(I'm running WinXP Media Center Edition SP2, Intel Core2 CPU 6400, 2.13GHz, 2GB RAM; my video card is an NVIDIA GeForce 7600 GT, and my screen resolution is 1680x1050 on a Gateway 22" widescreen FPD2275W LCD monitor.)
