Whenever ClearWindow command is issued to currently visible window , the captions stored in window are not copied to screen , since only toggle, hide window and delete window command do that right now , therefore data was out, with this PR , the caption are copied to screen and printed if there is some data and window was visible when Clearwindow was issued.

CCExtractor CI platform finished running the test files on linux. Below is a summary of the test results:

Report Name	Tests Passed
Broken	13/13
DVB	4/7
DVR-MS	2/2
General	27/27
Hauppage	3/3
MP4	3/3
NoCC	10/10
Teletext	21/21
WTV	13/13
XDS	34/34
CEA-708	14/14
DVD	3/3
Options	86/86

It seems that not all tests were passed completely. This is an indication that the output of some files is not as expected (but might be according to you).

Your PR breaks these cases:

• ccextractor -autoprogram -out=srt -latin1 85271be4d2...
• ccextractor -stdout -quiet -nofc -nodvbcolor 79a51f3500...
• ccextractor -stdout -quiet -nofc -nodvbcolor 767b546f96...
