Problems and Limitations
HP DDE Register Windows Problem
If you choose the menu items Show: Registers->General... or Show:
Registers->Special..., the windowdisplayed may be too wide to fit on
the screen. Resizing the window does not fix the problem.
The two alternatives to address this problem are:
• Install the libXm runtime patch PHSS_14873 or any libXm patch that
supersedes this patch.
The patch is available from Hewlett-Packard’s IT Resource Center.
For Americas/Asia Pacific customers: URL:

• You can examine the registers by using the HP DDE regs or dump
command.
HP DDE Problem with On Item Help
HP DDE may be unable to display help when you choose the menu item
Help: On Item. Instead, HP DDE displays the error message:
A request to the help server failed.
The desired help is not available.
This problem appears to occur more frequently if you select
Help: Overview before Help: On Item. You may choose to select
Help: On Item when you first invoke HP DDE if you expect to access
Help: On Item later in your debugging session.
HP DDE Problem with step -until Command in
Optimized C Code
If you use the step -until command (or Execution: Step
Operations->Step Until) to step to a line that resolves to more than
one instruction, the debugger will reach only one of the multiple
instructions. This problem is likely to occur, for example, in unrolled
loops.
The workaround for this problem is to set a breakpoint at the same line,
and then to use the step -return command (or Execution: Step
Operations->Step Out). This workaround allows you to continue to use
the step command for highlighting.
