Getting really frustrated here. I am writing a user guide using InDesign CS4. I created an .indb book file and added 5 documents where 4 of them are of approx 2-3MBs each. The main document is on approx 10MB, and the number of pages are 63. That's not a very large document, is it? I am not too eager to share this confidential document, thus I try to explain my problem thoroughly...
When typing within the main document the letters enters slower than syrup poors. I type, and then I must wait. It takes up to one second each letter! Does not matter if I type from the beginning of the document, or the end of it. Does not InDesign handle large documents, or is it a matter of content. All other functions and panels work as normal.
The main document consists of text, and screenshots in .png format styled with shaddow and frame. The text is formatted with a set of paragraph rules. In addition I have created a group of objects for textual Notes, consisting of an icon left to the text and then a grey background with frame surrounding the note text. This group has object, character, and paragraph styles attached to it. I cannot believe this is slowing the document down.
I perform some testing. I save the main document separately outside the .indb file, and then do several tests removing stuff in separate operations. After stuff is removed I try to type some text to see if typing still performs as syrup. Removing all screenshots in one operation, a table in another separate operation, then headers, note styles, and at last reducing content. After each removal operation I test typing from the beginning of the document, same place each time. None of the removals seem to have any effect to the document size. However, when reducing the 63 pages large document down to 45 the typing speeds up like a charm. Reducing to only 55 pages, however, make no difference at all. But why should reducing 10 pages from a 63 pages large document have such great effect? Is 50 pages the size limit for InDesign files? Or what?
I would be tremendously greatful if somebody could enlighten me in this matter.
