Some elements freeze SuperMemo while learning

Problem

While I learn Spanish, from time to time, some elements freeze SuperMemo. I need to wait 15-18 seconds for those elements to load. This takes away the fun from using the collection.

Comment

Your collection uses materials pasted from a dictionary website. Some of those files load very slowly. This problem occurs outside SuperMemo. If you try to open the same files in your browser, you will see a similar delay.

Workaround

Edit HTML, e.g. with Ctrl+Shift+F6, and add http: before // in BACKGROUND: url(). You can also remove the whole BACKGROUND attribute (up to the last semicolon). You will need to repeat that procedure for each slow-loading file.

Simpler Workarounds

The simplest solution would be to deprive those files of formatting. For example, Ctrl+Shift+F12 solves the problem instantly. Naturally, your items lose on beauty.

You could also copy-and-paste via intermediary application that would strip some of the problem causing HTML code. For example, in Windows, you can use Word Pad.

Browser comparison

Interestingly, while IE and Edge hang up on the file, Chrome first renders the content and only they "hangs up".

User's own workaround

Thank your for your help. I really appreciate that. I've arrived at yet another solution. However provisional it sounds, it works fine and saves tons of time spent on editing. I just disconnect the Internet and I do my repetitions offline. All the process goes smoothly and no single elements dares to hang up. best regards
