Extract files

If a file is too large, the detail list will show the rate of progress by a percentage. I made many installers before, there is no such problem, I do not know what cause it this time. When extracting a file, another box will show above the installer when the percentage is increasing, it read "Please wait while setup is loading......", the same as initialize a big installer, like this:

I do not know how, this phenomenon appears the first time.

Are you using a custom UI with MUI_UI?

Because I'm Chinese, I only translate the string "Please wait while setup is loading......" in the UI file "${NSISDIR}\Contrib\UIs\modern.exe" to Chinese. Also I edit the NSIS Error message box to Chinese by software. 6 files in "${NSISDIR}\Contrib\Stubs" are translated: bzip2, bzip2_solid, lzma, lzma_solid, zlib, zlib_solid. Is this problem caused by the UI File?

Make sure dialog 111 has the same styles in your UI as in the original UI.
