I use corel capture X5 for partial screen capture, OEL direct to corel paint and auto stitching. This programme resides in background and is brought into action to save by a hot key. I have tried a number of hot key options but firefox 4 always seems to give a black blank screen whenever screen capture activated, so one cannot capture screen. Corel Capture works perfectly in firefox 3. Is this a fundemental problem with way firefox handles graphics and interfaces with other programmes.
