Bugs in SIGNAL 4.02.04

Following are known bugs in SIGNAL 4.02.04.


Graphics

Hitting escape when the crosshair cursor lies between graphs on a multi-graph display (and is therefore not visible) causes program failure. Workaround: be sure the cursor is visible before exiting the cursor.

The G /O command 1) draws a blank graph when GTLIM or GFLIM are not set to AUTO and 2) draws traces one line below the axes when a buffer caption is present.

Zoom doesn't work on GO FT graphs. It splits the display into multiple graphs. Workaround: none.

The tracking cursor fails when the time or frequency origin of the underlying data buffer is not 0 (for example, a time buffer extracted from a sound file with time base preserved using R /T).

I/O

DartDisk acquisition or playback will hang if DartDisk and SIGNAL programs are simultaneously open. Workaround: close SIGNAL before launching DartDisk and close DartDisk before launching SIGNAL.

Programming

If a text line (such as the message lines provided to MSGBOX) begins with a system keyword, SIGNAL may execute that keyword as a command. Example: "return the box" may cause SIGNAL to execute the word "return" and terminate the command file. Workaround: rearrange wording to locate the keyword away from the beginning of the line.
