HC: "previous" and keyboard switches

[Peter Kupferschmied]

Two little problems related to my stack in development (running
HyperCard 2.3):

1) In my stack, the Hypertalk button script command "go to previous card"
shows a strange behaviour: if there are only few cards available, this
button cannot be used ad eternum and the disk begins to search
(nothing...) during several minutes! The button script command "go to
next card" does not make any troubles.
- Is this a well known problem (particular to HC 2.3?)?
- What is the best solution?

2) Sometimes, the keyboard settings (in my case swiss-french keys) are
changed to US during the programming work / scripting with HyperCard.
- Is this a well known problem?
- Does a special HyperTalk command exist to control the keyboard settings
or should I do this via CompileIt! and the Mac Toolbox?

Thanks for any advice!

You're probably using Cmd-spacebar to show and hide the menubar in HC.
Older systems use this key combination to change keyboard layouts.

Sys 7.5 (and maybe earlier versions of Sys 7 -- I'm not sure) uses
Cmd-spacebar to set the language to the next script and Cmd-option-spacebar
to set the language to the next language in the current script (according
to Apple Guide's "Shortcuts"). There's a checkbox in the Keyboard control
panel labeled "Use Command-Option-Space bar to rotate through keyboard
layouts", and it does enable/disable this action, but I still have problems
with Cmd-spacebar in HC (it doesn't work on either my home or work Macs
though I have seen Macs set up similarly where it does).

I stopped investigating when I found that Cmd-Shift-spacebar works to hide
HC's menubar and avoids the problems with keyboard layouts, scripts,
languages, et al.

I hope that helps.
