My problem is that my mouse won't double-click. I've uninstalled and reinstalled the mouse drivers and software, no joy. I've checked that the single-click hasn't been selected in folder options, it hasn't. I've duplicated registry settings from another PC that has a fully working mouse, still no joy, I fear that Windows has lost the meaning of double-click. Any ideas?? I'm running Windows 98 with a standard NEC wheel mouse through the PS2 port.
One possibility is that the mouse double click time is set too fast so that you cannot double click fast enough. Check the setting in the mouse properties and if it is set very fast just set it slower and see what happens.
