When I try to use the Append function I get an index out of range exception in the function
When you leave AllowConcatenateExceptions set to false, you won't see an exception at all and the function will freeze indefinately until you stop debugging.
See the example code. Doesn't matter what PDF I use here, crashes every single time.
This functionality used to work in older version and most of our customers are still using version 126.96.36.199. For this German customer we had some problems translating umlauts and other German characters and version 188.8.131.52. translated these to block characters, so we switched to version 184.108.40.206. That fixed the problem with the umlauts They didn't use this functionality that used the Append function yet, but now they switched it on causing a crash.
Our licence for Aspose is until 05-27-2011, but the person being able to extend our licence isn't in the office for a while. Could you please help anyway?
