[ct-user] stuttering cw w/ ct-Win

[NL7Z]

I have been trying to find out why I get "stuttering" while using ct-win - the old dos versions never did that.
Does anyone know if there is a way to dedicate more pc resources to the program or the port? The problem is bad enough that I cannot use CT-WIN for generating cw. It seems to be random, but it will usually truncate at least one letter during a cq.
Thanks
Kevin
