[Swftools-common] Problem with Concatenate

[MK At Games2win]

Hi All,

I'm trying to use swfcombine.exe to concatenate two SWF files.

The call made is :
Swfcombine -o test.swf -a file1.swf file2.swf -v

File1.swf is a single-frame SWF, whereas file2.swf is 30 frames.

On running the above command, the merge completes, but I always get the
following error :
swf_Relocate: Mapping id (89) never encountered before in DEFINESPRITE

The result of this call is that sprites of a specific frame originally from
file2.swf always get displayed incorrectly.  The rest of the test.swf runs
perfectly. 

Any ideas as to why this happens?

Thanks and regards,
Mahesh
