1) The Zoom and drag controls are available in the following cases:
– “Allow native dragging” option is disabled in Preferences;
– The SWF file is played back right now in SWF & FLV Player;
In fact, resizing option is not available for FLV files playback.
2) You can’t see the “sizing control” until you point a mouse cursor to the left bottom corner of the SWF & FLV Player window. It is pre-designed option of SWF & FLV Player. When the cursor changes its layout, click the mouse button and drag it.
