Ok, so I've used mIRC for several years, but I just started having this problem recently. Whenever I maximize a chat window within mIRC, instead of maximizing completely and docking into the main mIRC window, it just expands to fill the mIRC window without docking in. This means if I then resize the main mIRC window, it doesn't resize with it, it just stays whatever size it happened to be. I'm using version 6.03. Anyone know how I can fix this? If I'm not clear, let me know and I'll try and post a screenshot somewhere.
