I can’t remember what all the problems were but it was significant enough for me to stick with the FPC blue screen text mode IDE, and that has been working fine. I’m not sure if it’s because I have a lot of $Mode TP units mixed with FPC units, or if it’s that some of the Lazarus procedures and functions have the same name as other procedures and functions but don’t work the same way… I would have to just try it again to see what was up. I may make another try with Lazarus, but I’m hoping to find a solution that works with just FPC, as I know for a fact the rest of my project has no problems with that. <o:p></o:p></span></p><p
