problem with idle handler

Hello,

I have problem with idle handler. My application displays some info on the virtual memory and allows to puge the inactive memory with a button. Without idle handler connected, no problem but with the idle handler, the command blocks. but if I click on the mouse button, the command ends! ???


on idle theObject
	readInfoMemoryUsage()
	return 5
end idle

on clicked theObject
	if name of theObject is "purgeMemory" then
		do shell script "purge"
	end if
end clicked

on readInfoMemoryUsage()
	-- code for display the info
end readInfoMemoryUsage


Sorry for my bad english…

The problem is perhaps the “purge” command, because another command doesn’t block… :confused:
