Note for Mac OS X 10.5 & 10.6 users

Folks,

We have learned of a nasty bug in Apple's Java Virtual Machine (JVM) that can affect InterMapper users. The symptoms are that the InterMapper GUI appears to freeze: the windows do not respond to mouse or keyboard, and people report that they have to force quit.

It only happens when using OSX 10.5 or 10.6 with Java version 1.6.0_20. (installed with Java for Mac OS X 10.5 Update 7 or Java for Mac OS X 10.6 Update 2) with InterMapper (and RemoteAccess) versions 5.2.6 and earlier. We believe we have found a workaround, and will publish this as soon as possible as version 5.2.7 (early next week).

[For the terminally curious: This can occur when a window opens with a resizable, modal "sheet" to collect information. What actually happens is that the sheet opens *behind* the current window: everything continues to operate normally, but you cannot see the sheet to operate it. We have submitted a reproducible bug report to Apple, so we expect this will be fixed at some future time.]

As a workaround:

- Don't install updates to Java (versions listed above) on your Mac. Versions 1.6.0_17 and earlier seem to be OK.

- If this happens to you, you can usually use the Escape key to close the sheet and try again.

- Wait until we release version 5.2.7 next week.

Note: This same problem also affects the 5.3 beta builds that are out for testing. The same workarounds are available, and we will have a more stable fix when we ship the final version.

If you have further questions, please contact support@dartware.com. Thanks.

Update: The release of InterMapper 5.2.7 on 14 June 2010 solves this problem; version 5.3 released on 16 June also contains a fix for this problem.
