The following are known issues when using Firefox, Safari®, and Opera® browsers:

• Not all browsers support all of the options that you can use in Maintain. While VBScript works fine in Internet Explorer, it does not work for non-Microsoft browsers, like Firefox, Safari, and Opera. If you are developing an application that you might run using one of these browsers, use the JavaScript or Maintain code options in the event handler editor to create your events.
• The ActiveX Read/Write Grid cannot be used with Firefox and other browsers that do not support ActiveX controls. The JS Grid control can be used with these browsers.
• In Firefox Version 3.6.3 and higher, right-clicking on a record or data area of an Update Assist application displays a browser menu.
• If you run a Maintain application from applaunch.htm with Firefox, exiting the application will show another copy of the navigation tree in the procedure frame or window. Only use the tree in the left frame of the original browser window to launch additional applications.
• The Maintain Application Debugger does not work with Firefox.
• You cannot disable images and other controls using JavaScript when using Firefox.

The following are known issues when in the Maintain Development Environment:

• A stand-alone computed date field bound to an edit box, with the format in lowercase (for example, stk1.date/mdyy='12/15/2010'), will not currently display the pop-up calendar at run time. To work around this issue, you will need to change the date format in the Compute to uppercase (for example, MDYY) and delete the original edit box control. Replace it with a new edit box which you can then bind to the field with the uppercase format.
• When copying and pasting controls in Version 7 Release 7.01, it is possible that some of the controls will have duplicate tab order numbers. In order to work around this issue, use the Tab Order dialog box to manually assign the desired tab order.

  This issue has been addressed in Version 7 Release 7.02.

• An event handler for the OnTHLClicked event for the Grid controls can interfere with other event handlers on a Winform. To work around this issue, enclose your event handler in the following JavaScript if statement:

  if(updn == 0)

The following are known run-time issues in Maintain:

• Some compiled Maintain procedures may run more slowly in Versions 7.7.0x. As a workaround, use the uncompiled procedures by removing or renaming the .fcm files and invoking your main procedure with the MNTCON EX command.
• Do not use decimal formats (for example, D20.2, F10.22) in a stack with ibivalidation set to yes. This currently fails at run time with an incorrect validation error stating that the entered value is not a valid integer.
• If there are JOINs in effect for a data source that is being accessed by Maintain while using SU, you may encounter the following message:

  (FOC03766) Client/Server mismatch for file: (filename)

  This is because SU does not use the JOINs. Therefore, it returns a different number of fields than the local user has passed. To prevent this error, you can clear JOINs before issuing the Maintain command or add any additional data source file to the MAINTAIN command. For example, adding MAINTAIN FILE VIDEOTRK AND CAR. In the latter case, Maintain will automatically remove the JOIN from the local side and compare based only on the host file.
