Using Think pascal 4, I get the error ... "project.Rsrc could not be opened. It may be missing or in use by another project" This never happens the first time I run a project., only the 2+nth time.

If I open the project, build and run, it works, but if I then try to run it again, or make a change and then build and run again, I get the error.

Some projects never have this problem and always work.

Anyone know what I'm missing? I can't find any difference between the projects that work and the ones that don't work that would create this issue.

Thanks for any insight.
