I finally configured LHelp as a CHM help viewer in my development Lazarus. I downloaded Marco's CHM snapshots linked here: https://forum.lazarus.freepascal.org/index.php/topic,52437.0.html There are 2 updates from Andrey Sobol. I downloaded them, too. LHelp opens correctly, although slowly for the first time. There is a strange flicker. First an empty window shows up, then it disappears. A little later the actual help window with contents shows. Anyway, then it works well and the documentation itself has improved, too. Nice!
When I close LHelp, it asks if I really want to do it. Yes, I want it. Then LHelp leaks memory. See below. IIRC it does not leak when I start it standalone. It is caused by the IDE integration. Andrey Sobol and everybody who develops LHelp, please use the Debug buildmode I added there some time ago. All debug flags should be on when developing code. I tested with Linux 64-bit. IDE is built with LCL-QT5, I guess the same is used for LHelp.
