Subject totally abnormal CPU usage when dBase is idle From Gaetano <gaetanodd@hotmail.com> Date Sun, 13 Dec 2020 07:11:02 +1000 Newsgroups dbase.getting-started This probably belongs to bug reports but I wanted to check if anyone was noticing the same pattern before I post it there. I was wondering why my computer fan was unusually loud and looked at the program manager. dBase 2019 was on top of the list with a **permanent** usage of 2.5-3.5% of CPU usage the moment I open a PRG in the source editor without doing anything to it, even after minimizing dBase (with focus on the Source Editor). The usage drops any time the editor loses focus and the CPU cycles increase with the size of the PRG file being open: 0.5-1% with a small PRG of just 80 lines. 2.5-3.5% with an 800-line PRG. 11-15% for a PRG of 5000 lines 20% for a 20,000 line PRG I just copy-pasted the code of the previous file at the end of the PRG for the last two samples as I don't have PRG's that large. The CPU usage ramped up with every paste operation. Give focus to something else, e.g. go to the Navigator, and the CPU usage drops to normal idle levels of 0%-0.2%. Give focus back to the Source Editor window and the usage goes up again. Is anyone else able to reproduce this?
