Applet problem in JRE 1.6

I have an applet working well in JRE 1.5+. I've recently updated JRE to 1.6 and that applet has an inconvenience, if don't say as it's a problem. Once applet loaded, only the first control (a textfield) is displayed, others are invisible until I click (randomly) on the blank space, or use TAB key to navigate around.

Is it a bug? Or something incompatible? Please tell me why. Thanks a lot!

I am having similar issues since the upgrade to JRE 1.6. The applets will freeze or repaint only partly.We are using IE 6.0.29 on XP SP2.Have you found any resolution?Thanks for your help.

I have looked on the bug database but haven't found anything similar for Java 1.6. I would submit a bug but am still unable to verify steps to reproduce the error 100% of the time.
