Use of IDE lazarus / 9-Editor ---------------------------------------------------------------------- John_Nicol · 2019-09-05 01:12 I have a recurring and very annoying problem with the IDE loading up either an application file - form and/or unit  file that has been in use recently or a New Application with blank form.  When I am editing the unit I have loaded, and run it, the compiler grabs the unwanted blank form.  How can I get rid of these extra, free loading, applications which prevent use of the IDE without considerable effort to hide them?  Thank you ---------------------------------------------------------------------- valdir.marcos · 2019-09-05 04:04 Quote from: John_Nicol on September 05, 2019, 03:12:06 amI have a recurring and very annoying problem with the IDE loading up either an application file - form and/or unit  file that has been in use recently or a New Application with blank form.  When I am editing the unit I have loaded, and run it, the compiler grabs the unwanted blank form.  How can I get rid of these extra, free loading, applications which prevent use of the IDE without considerable effort to hide them?  Thank youIf I could understand you correctly, you are talking about a current feature of Lazarus IDE: Compile unit without project https://forum.lazarus.freepascal.org/index.php/topic,46354.msg330080.h tml#msg330080 ---------------------------------------------------------------------- Martin_fr · 2019-09-05 08:35 I am not sure what you are describing, or what you try to do. But in case that: You are trying to edit a single *.pas file and then trying to compile it. The IDE is build to always require a project open. You can not close the project without opening a new one. So if you close all the open editors, and load your file -> the project that was last open is still open (even if not visible). If your *.pas file is a "program" then make it a project of its own?
