I just upgraded to the new 1.3.0 but I found an initial issue.
When running any Lua project file from the IDE I get a message like the following in the Output panel:
Program starting as Desktop application.
Program 'luart.exe' started in 'C:\Users\steve\OneDrive - XYZ\Documents\LuaRT\examples' (pid: 2744).
'C:/Users/steve/OneDrive' is not recognized as an internal or external command,
operable program or batch file.
Program completed in 0.10 seconds (pid: 2744).
It suspect that Windows paths including spaces are not properly handled. This was not happening in previous versions.
Another suspect is that this is due to calling luart.exe instead of wluart.exe when running a Desktop app.
Running the same app from a CMD console using wluart.exe is working.
