thanks
after sending a question
I tryed to compile *.java files in directory  where java is.
everything was nice. But I needed to work in java dir. Not the best variant :))

Can you please answer a question?

I am creating applets already :). And I need to test it(recompile and run). That's ok.

I open html with applet tag - applet is there. I see where to repair something.

And make repairs in xxx.java file. then recompile it. open html again and previous variant. Even if I delete xxx.class file IE still shows previous version.

Is it kind of cache????

Sorry for my English. And for such stupid questions :). But I need to start :))

Thank in advance

Roman

Ctrl-F5 IE to refresh properly, otherwise you'll get a copy from the cache.

I know about F5. I am not so stupid :).
Applet reloads and I see old one

F5 and Ctrl-F5 have *very* different effects.
