I tested in JDK1.1, it ran fine, however in JDK1.1.1, this was definitely
a bug. This problem doesn't exists in Solaris.
Please see the attachments for a reproducible test case.
-------------------------------------------------------------------------------

The bug report that appears to be very close to what we are experiencing is 4032124.
It appeared to be fixed in jdk1.1 but has returned in jdk1.1.1.

The following is the code to reproduce the problem.

 
To make this happen do the following:
1. run testDlgs
2. select dialog #1
3. select dialog #2 while in dialog #1
4. cancel dialog #2
5. cancel dialog #1
This appears to work but without exiting the program do step 1-5 again. This time
It will freeze the frame when canceling out of dialog #1.

Customer added the following problem in the same attached test cases. (04/24/97)


Hi
Its carl struthers again with more pain. We have another bug that is critical an very easy to reproduce using the same test code we sent before. It causes the focus manager to rip. The following is the method to reproduce the problem.

1. Start testDlgs.class using jdk1.1.1
2. Select show dialog
3. With mouse set focus to another window other than the testDlgs window
4. Now set focus back to testDlgs dialog box
5. Depress tab key. ( this will cause a rip to occur in the dos window

Important note: THIS DOES NOT HAPPEN ON JDK1.1

Additional note from the customer (April 30, 97)

Hi
This is Carl Struthers at FTP Software Inc. and I am just checking in to see whether there is any status change of bug 4046833. This is the chained modal dialog hang.

There is one new observation that may mean something but again may just be noise. This is that on fast machines 200mh pc's the problem does not appear to happen as frequently.
