After starting lazarus (either via a project's *.lpr or the icon on the desktop), the IDE
appears as expected but would not react upon any interaction (all menues except 'file' disappear upon the first click).
A check with the Process Monitor revealed that it seems stuck in an endless loop calling
IRP_MJ_CREATE C:\(mytempdir) --> SUCCESS
IRP_MJ_DIRECTORY_CONTROL C:\(mytempdir)\LazarusMain01-* --> NO SUCH FILE
IRP_MJ_CLEANUP C:\(mytempdir) --> SUCCESS
IRP_MJ_CLOSE C:\(mytempdir) --> SUCCESS
these four lines reappear and reappear and reappear .... (taking ~0.04s)
checking (mytempdir) manually: the requestes file exists, but with 0 bytes and locked. After killing Lazarus (necessary, it would not react upon close), I can delete the file (i.e., not locked any longer).
what I tried so far:
* another project --> same
* reinstall Lazarus --> same
OS: WIN 10 home
Laz 1.8.4
FPC 3.0.4
Seems the access to the temp-file is broken. Any ideas what has gone wrong or what to try next?
