Hi Roberto, | I've noticed that the WinHugs application eats 100% of the available CPU even | when it isn't doing any work, just blinking the cursor!!! This is a well-known problem with the WinHugs user interface, and is one of the reasons why use of WinHugs has been discouraged. The user manual comments on this, for example, but perhaps the wording should be stronger! WinHugs was even left out of the Hugs distribution at one stage because these problems were felt to be too severe. But people still asked for it and so WinHugs made it back into the distribution ... The WinHugs interface eats CPU because of the style in which it was written. The original author of the WinHugs GUI, Pepe Gallardo, did produce a newer version that avoided these problems, but I don't know what happened to it; I'm not aware of a source for it on the web. Pepe, if you're out there, I'm sure folks like Roberto would be happy to hear from you! In the meantime, I wouldn't recommend using WinHugs for everyday use. All the best, Mark
