FREQUENTLY ASKED QUESTIONS
45. "Save as" doesn't seem to work. Why not?When you save a substack, it is saved *with* its mainStack into a file. If you then reopen the stack, what you will see is the mainStack, *not* the stack you were editing. The general rule: unless you are preparing to distribute your stack, don't use "save as..." to make a backup of it. Instead, use the normal OS file copying feature to make a copy of it, or use the "clone" command and save the clone into a new file.
46. Why can't start editing groups or edit button scripts?Strange behavior can occur if there are multiple stacks with the same name loaded. Try renaming one of the stacks and then try use 'topLevel "oldname"' to see if a copy of the stack exists.
47. Cut/copy/paste doesn't seem to work. Why not?Cut/copy/paste of text selections doesn't work if you have your window manager set up to use pointer focus. See the README.install file for instructions on how to change it back to explicit/click-to-type focus.
Strange behavior can occur if there are multiple stacks with the same name loaded. Try renaming one of the stacks and then try type the following into the Message Box to see if a copy of the stack exists:
Pointer focus is an obsolete technology inherited from the old Sun
and Apollo workstations where graphical displays were used primarily as
a way to open multiple terminal windows. It does not work well with
true GUI applications which open dialog boxes and support keyboard
traversal among controls within the dialog boxes. Therefore, using
explicit (click-to-type) focus policy is strongly recommend with
MetaCard. Explicit focus is the default for mwm, olwm, NeXTstep, the
Macintosh, OS/2 Presentation Manager, and MS-Windows. Instructions for
reconfiguring olwm and mwm to use it can be found in the file
To improve performance and reduce memory usage on both the client and
server, you should also crop your images down to the minimum size
necessary. To crop an image, click on a painted on area with the
pointer tool, and resize it using the resize handles.
The best solution to this problem is to use the same colors for all
of your images, and to select colors for all the other objects from
this palette. You may also want to color quantize any images in your
stacks to reduce the number of colors they use. Most image conversion
packages have filters for performing these operations.
You can force a stack to be double-buffered at all times by setting the "alwaysBuffer" property of the stack to true.
