ofSystemSaveDialog changes current directory on Windows only

Hi all, I noticed that when we use the ofSystemSaveDialog() function on PC

it changes the getCurrentWorkingDirectory() and this breaks the path directory in OF

So when you try to load an image or save an xml OF can't find the path because it looks to the directory you saved your files.

This only occurs under windows.

on Mac getCurrentWorkingDirectory() points to the same spot after the dialog

///

The problem is inside the ofSystemSaveDialog in the ofSystemUtils.cpp

#ifdef TARGET_WIN32
    wchar_t fileName[MAX_PATH] = L"";
    char * extension;
    OPENFILENAMEW ofn;
    memset(&ofn, 0, sizeof(OPENFILENAME));
    ofn.lStructSize = sizeof(OPENFILENAME);
    HWND hwnd = WindowFromDC(wglGetCurrentDC());
    ofn.hwndOwner = hwnd;
    ofn.hInstance = GetModuleHandle(0);
    ofn.nMaxFileTitle = 31;
    ofn.lpstrFile = fileName;
    ofn.nMaxFile = MAX_PATH;
    ofn.lpstrFilter = L"All Files (*.*)\0*.*\0";
    ofn.lpstrDefExt = L"";  // we could do .rxml here?
    ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_OVERWRITEPROMPT | OFN_HIDEREADONLY;
    ofn.lpstrTitle = L"Select Output File";

    if (GetSaveFileNameW(&ofn)){
        results.filePath = convertWideToNarrow(fileName);
    }

#endif

the way to deal with this now is after the

: saveFileResult.bSuccess or before you need to load or save something in data again.

you put once:
ofSetDataPathRoot(DEFAULT_DIRECTORY);

the DEFAULT_DIRECTORY is a string I initialize in setup with

DEFAULT_DIRECTORY = ofToDataPath("",true);

Not sure how we can solve this from within the function

Start in ofSystemUtils.cpp at the Windows implementation of ofSystemSaveDialog(), and reproduce the working-directory change on Windows. Verify that opening the dialog does not alter getCurrentWorkingDirectory(), then confirm image and XML paths still resolve afterward; no test file is mentioned in the issue.
