I also forgot to mention that there seems to be a spacing issue when horizontal and vertical radiobutton questions are intermixed. When the items are all vertical, there does not seem to be an issue, but when one of them is horizontal, a large space separates the horiztonally oriented item from the one above it.
As an aside, spacing also seemed to be an issue with the survey pages. When I made the scripts in inquisit 3 on a desktop PC, everything looked fine, but when I ran the scripts over the web in Inquisit 4 and on my mac in inquisit 4, at the top of each surveypage a huge gap appeared between the page caption and the caption for the first item. I played around with all of the item spacing, font sizing, etc options, but wasn't able to get the gap to disappear. To resolve the problem, I deleted the surveypage caption, and simply added it to the caption of the first item on each page.
Finally, in Inquisit 3, when a radiobutton item was oriented horizontally, the spacing between the options was customizable. This was both good and bad. When I am working with it in 4 on my mac, the spacing between options (it seems) is standardized to the largest option. This is very nice, with the exception that with a 7 option likert scale including "neither agree nor disagree" as the center choice, the buttons run off the side of the screen. Is there a workaround for this?
I've attached one of the files on the chance that it might prove helpful.
Anyway, thanks for the help.
