I didn't use the 4/18 zip, but I see from the release thread that 4/19 fixes a hud issue. The only reference I have of a hud issue is a thread
here which was locked. My issue is a bit different.
Using the 4/19 zip, if I minimize my game window and then tab back into it, I lose my UI, including the MQ chat window. It looks exactly like if I had pressed F10 - hud is still up, character is still in game. Pressing F11 will then toggle the fps indicator on and off, but the rest of my hud always stays on. Everything seems to be working ok, other than the display - the character responds to commands, and I can sit and camp out just fine. I have to exit the game completely and restart it to get my UI back. This is repoduceable across several characters and 3 boxes, both with and without EQW. Unloading and reloading multiple plugins doesn't change anything. Starting without MQ2Hud loaded doesn't change anything.
