Forums Scripts & Popups adding a visual counter on a %loop

I have a standard %loop reading lines from a txt file, there are (at the moment) 35,000 lines in the file

so the %loop is very rapid. in the loop, if I put " /echo -s %loop " in each loop (or pref updating a single line of a @window), mIRC stops the update message after 3-4-500 lines (continues to run the script). presumably the /echo takes second priority to running the script (or something)

is there any way to set it so mIRC will make sure it continues to run (display) the /echo line?
