10.0v4

Customer reported platform

Steps to reproduce

1) Create a new 10.0v4 HieroPlayer project 

2) Import any clip, add to Timeline, cut it in half and slide 2nd clip to right and

Save As > Player_v01.hrox

3) Make any change to Video 1 Timeline so that an autosaved .hrox will be created

4) Save As> Player_v02.hrox and Close it

5) Re-open Player_v02.hrox and note that clips can be edited as expected 

6) Go to disk and rename the autosaved project from

Player_v01.hrox.autosave to Player_v01a.hrox

7) Open Player_v01a.hrox and try to edit, e.g. slide clips in Timeline on Video 1

8) BUG: clips cannot be edited 

Workaround

Reproduced by support

Expected behaviour

HieroPlayer autosaved projects should be editable in the Timeline, just as projects
are editable when you Save As.

Actual behaviour

Autosaved HieroPlayer projects are not editable in the Timeline, making autosave
limited in usefulness.

NOTE: You can Add New Tracks, Scan for Versions and Refresh Clips. This bug only affects
editing clips in the Timeline, as you could  HieroPlayer 1.9v1
