LiveCode Forums.

Hi,

I am beginner in livecode, I am open a pdf using shell script, when the pdf is loads, I can't doing anything on stack also I have placed an timer in the stack it's also be stopped. How i overcome this problem using Thread. or is it any alternative method for this problem.

Rather than "shell" you can try "open process" to make asynchronous calls to processes with which you can communicate. You might even find that "launch" will do if you don't need further interaction.
