What I tested and works for me with x32 PSPad Windows 10 x64 - tested Multiuser 1/0 (multiuser has no influence) Windows 7 x64
In both cases I see message send and message receive I tried to run PSPad from "network". There was question for the first instance start, but another file opening with context menu was without problem. I am little confused. I need to find a cause or rewrite whole file handling. -- <https://forum.pspad.com/read.php?6,69840,69872> PSPad freeware editor https://www.pspad.com
