slit Hello. Please avoid duplicate threads. Only one macro can run at a time in a single instance of the program. To use multiple files, launch multiple Keyran instances using the normal launcher and assign a different file to each.
What's the freezing issue? I can only assume that the macro structure is incorrectly created, causing the freezing. Please send a screenshot or macro files, and also send the log file https://keyran.net/en/wiki/?sp=38
From what you wrote, there are no bugs in the program.
