[OU] JavaScript Question

[Joel Hammer]

Well, I think I know what is happening, but not why.

When you try to immediately "unclick" a button after it is clicked,
opera will not to it (6.02 in linux). You have to have a slight delay,
say 600 milliseconds, before you are able to unclick the button.

No big deal but:

1. You have to make explicit accomodation for this in your javascript.

2. IE doesn't have this problem. So, since most web sites are written
for IE, this is the sort of minor problem which might make opera less
able to browse.
