I updated TATARA7 to 7.292.
The improving points are as follows.
-library was updated.
It is mainly for windows 8.1.
-The bug of selection of New Dialog was fixed.
-The selection of file type was updated.
-The bug of interface design was fixed.
Thereby, operation of TATARA7 on Windows8.1 was stabilized more.
Moreover, I checked operation of the TATARA 7 on Windows10 Technical Preview. Build which was verified is 9926.
The user of TATARA7 can use for free.
