[OS X TeX] pdf viewers: pop-ups at hyperref links

Sun Jul 10 19:51:18 EDT 2022

Hello Roussanka,

I’ve just done a little more investigation. If I’m in a 200 page document, I always have to wait until the pop-up appears before I command-click; otherwise I get the tiny mutant window. If I’m in a 50 page document, I can often command-click just before the time when the pop-up would appear and get the second window in the form I want. If I command-click immediately after hovering over the link with the cursor, I get the tiny mutant window. I wonder if this is a timing issue — for example, maybe something must happen in the code between the time when you hover over the link and you command-click in order for it to work correctly. I have an older Mac Mini with a 3 GHz Dual-Core Intel Core i7 and a not very fast GPU; maybe the machine is just too slow. It takes a second or two just for the pop-up to appear in both Skim and TeXShop.

If you hover the cursor over the link long enough for the pop-up to appear and then do a command-click on the link, Skim displays off to the side a window of a full page width view of the lemma or whatever, but only maybe ten lines long, and it’s scrollable vertically. Then I can examine the text on both pages side by side and determine whether or not, for example, the lemma really does imply what I said it does.

>> The one thing that annoys me about this though is that I first have to wait for the pop-up to appear. If I command-click before the popup appears, a tiny useless window pops up. I believe that at one time I used to be able to do a command-click before the pop-up appeared and it worked properly, but at some point it stopped working properly.
