I've built a rather large mail merge Word document that draws on the maximum of 256 columns of data from an Excel file. Each of these columns is used and most of them are used for conditional text. (some text is displayed only when the value in the column is higher than 0).
Now the mail merge process works fine (it takes some time, but that is to be expected), but when I work in the 'master' Word document, there is extreme lag in typing (up to 5 seconds and a full white screen), roughly every 5-10 seconds. This happens both when a link to the Excel data file is active and when it's not.
I have tried changing the default printer (as someone on the forum suggested), but that didn't help. All posts on the forum seem to be on the slow speed of the actual mail merge itself, but that is not my problem. Working in the Word document itself is virtually impossible with this lag.
Both the Word and the Excel file may be fairly large in content (Word: 6 pages full of conditional text, Excel: 256 columns, 40 rows), but they are not in size (both roughly 70 - 90 KB).
Does anyone recognize this problem? And do they have a solution for it? That would be greatly appreciated!
