IE 5 (and even 6) bug:

I am running IE6 (and before it IE5 which had the same problem) on a Dell OptiPlex GX110 (P3-something with 256 MB of RAM on Windows 2000). Right-clicking on a page to view source, open a link in a new window, save a picture, etc. works, but when I right-click, the popupmenu takes about 5 seconds to come up, instead of instantaniously. What's up?
