Hi
Not seen this happen before. I take it that none of the FX boxes on the timeline are blue where you made cuts?? If this behavior happens every time you make a cut and export the project, set up a couple of unimportant clips on the timeline ; make some cuts in them and then check an export to see if the ?bug you are reporting is present.
If the exported test video still shows the error go back to the project and from the File menu select Save Portable Project As Follow the prompts. This should save both **the clips and a vpj file** to the designated folder.
Upload this folder to Dropbox etc. as mentioned in Borates link. Dropbox will supply a link for you to post to the forum. Include details of how you exported your project and the version of VP that you used. This will enable other forum users to load your test project, check it over for obvious errors and export it with your settings to see if they reproduce what you are getting.
